IMPROVEMENT IN CLOTHES-PIN MACHINES.

Specification forming part of Letters Patent No. 147,277, dated February10,1874; application led i September 8, 1873.

To all whom 'it may concern:

Be it known that we, HARVEY LocKn andl EDWARD W. Locrm, both of the cityof Grand ltapids, coimty of Kent and State of Michigan, have invented anew and useful Improvenient in Clothes-Pin Machines, of which thefollowing is a specication, reference being had to the accompanyingdrawings and the letters of reference marked thereon, and the same aremade a part of this specification.

The nature of our invention relates, first, to the arrangement ofspindles which hold the stock in a circular rotary frame, 1n combinationwith a series of circular saws and stationary cutters 5 second, thecombination and arrangement of a rotary feed-wheel with the revolvingspindles, for the purposes described; third, the device for slotting theclothes-pins, used in combina-tion with the spindles of theturning-lathe of the machine.

In the drawings, Figure l is a front upright view of our invention. Fig.2 is one of the spindles with pulley rigidly attached. Fig. 3 is aslide, which, in the machine, is attached 'to the spindle, and with thestationary spindle and with the stationary cam gives it its longitudinalmotion. Fig. 4 is a side, upright, perspective view of our invention.Fig. 5 is atop view of a portion of our invention, showing arrangementof the circular saws, stationary cutter, clutch, spindles, and feedingdcvice. Fig. 6 is a sectional view of t-he clutchwheel 102 and thestationary cam which operates the jaws of the clutches CIC.

In Fig. 4, Z isa shaft supporting the pulleys B, @,f, g, and 4f. Thepower may be applied to this shaft in any suitable manner. A band ispassed over pulley B and pulley D, which last-named pulley is rigidlyattached to the arbor ofthe circular saws S S S, as shown fully in Fig.l. On the shaft Z, just back of the pulley B, is a pulley, 4, (shown inFig. 1,) which is connected by means of a cross-band to pulley Bf, whichis rigidly attached to a shaft, upon which shaft is a friction-pulley,F. Friction-pulley F engages with and operates friction-pulley F', aportion of which pulley is cut away in Fig. 4 to show the arrangementofthe oval gearing. O is an oval cog-wheel slides revolve.

upon the shaft of friction-pulley F which cogwheel engages with andoperates a similar wheel, O. The shaft upon which the oval wheel isplaced pierces the oval wheel near its smallest part, so that the cogson the largest part of one engage with those of the smallest part of theother, and the cogs farthest from the shaft of the one engage with thecogs nearest the shaft of the other, the motion being conveyed from O toO. The arrangement above described causes the shaft of O to revolverapidly at one part of its revolution, and slowly at the opposite. Italso causes alternate rapid and slow motion to all parts of the machineoperated from the shaft O. To the shaft of O is attached a small pinion,(shown in Fig. l by t,) which engages with and operates cog-wheel l),and thereby P and T. T is attached to the shaft of the feed-wheels u u,and thereby the alternate slow and fast motion is conveyed to thefeed-wheels. The cogwheel T engages with and operates the cogwheel T andshaft to which it is attached, and thereby the rotary motion is given tothe circular frame Y Y and wheel t1, and miter-gearing o and thecircular frame Q12. The cogwheels T and T are the saine size, andtherefore the feed-wheels u u, frame Y Y, and cogwheel e, and frame o1o2 revolve with the same rapidity, as does also the miter-wheel w1,which engages with and is operated by said Wheel o. The circular frame YY supports a number of spindles, each one constructed with the pulleyc', as shown in Fig. 2. o1 t2 also support the saine number of similarspindles, as. shown. Fig. 3 is a slide provided with a pin, la, whichslides in the groove Hof cam-wheel XV. (Shown in Fig. l.) Itis providedwith the projections n n, which iit into the groove m of the spindle-oneon either side-in such a manner as to allow the spindle to'revolvefreely, and yet to prevent the spindle from having any longitudinalmotion separate from the slides. XV is a stationary cam-wheel, aboutwhich the R is a similar cam-wheel, and

the grooves H and H are so constructed that the slides holding oppositespindles arecarried forward toward each other at the saine instant, andthe feed-wheels are provided with A'rnN'r hrrren notches, as shown,which notches are so arranged that a block is brought into position tobe caught between the spindles at the time they are brought toward eachother by the cam movement above described. The blocks to be turned intopins rest between the side pieces of the hopper and upon parallelinclines, one of which is shown in Fig. 4 by J, and slide down upon thefeed-wheels, and are carried forward, one at a time, by the notches inthe feed-wheels, to the spindle, as described above. On each side of thehopper is a metallic or other spring, which presses against the end ofthe block, and they together hold it in their grasp, so that it cannotfall or become displaced before it is seized. by the spindles. The blockis carried downward by the spindles and caused to revolve rapidly, andpasses over the saws S S, which cut it into the required form in therough, when it is carried past the stationary cutter l, (shown in Fig.5,) which finishes it ready for slotting.

The arrangement of the gearing above de-l scribed is such that cog-wheelO revolves as many times to one revolution of the shaft carrying thespindle-frame as such frame carries spindles, and as many times to onerevolution of the feed-wheels as each feed-wheel has notches.

The number of spindles maybe varied in different machines. y

The miter cog-wheel lv engages with and operates the miter-wheel w1.rlhe wheel w1 is provided with a series of clutches, C, equal in numberto the sets of spindles. Each clutch is rigidly attached to the wheelwl, and provided with a jaw, as shown in Fig. 6, by 3, hinged to theclutch in such a manner that it is opened and closed by means of the pin6, which pin 6 slides in the groove of the stationary cam wz. The cam2v2 is constructed in the same manner as the cams W and R.

By an arrangement of the grooves in camwheels XV and lt, the spindlesare withdrawn from the t-urned clothes-pin shortly after it has passedthe saws and cutter.

The cam-wheel to2 is provided with a groove running entirely around it,a part of the way being nearer the inner side ot' the wheel, and a partof the way nearer the outer side of the wheel. The pin of the jaw, whilepassing in the groove toward the inner side ofthe wheel,

closes the clutch, and while passing in thev groove toward the outerside ofthe wheel the clutch is open. rlhe arrangement of the canigrooveis such that the pin of the jaw passes from the outer to the inner sideof the camwheel at the point where the spindles are withdrawn from theclothes-pin, closing the clutch, which is then in position to clasp theclothes-pin, and the pin in the clasp of the clutch is carried by therevolution of wheel w1 until it is passed by the slotter Sf, when thepin of the jaw C again passes toward the outer side of the wheel wl,opening. theclutch and releasing the finished pin.

The slotter is provided with two or more knives or cutters, which trimthe outer end of the slot into the desired form. The arrangement ofwheel w1 is such that the slow motion is given to it as the pin isbrought in contact with the slottin g-saw, and the arrangement of therevolving frames that support the spindles is such that they have theslow motion as the stock is carried over the saws S S S and cutter l.The arbor of the saws S S S is sup ported by the frame 7 7, which ishinged to the part 9 by means of a rod passing through the part 9, andhung as shown in Fig. 4.. This allows the saws to be adjusted to stockof any size by means of the set-screws a and a. a passes through thepart or support E, and against the frame of saw-arbor S S S; and a.passes through the frame of the arbor against the frame of the machine.L is a lever turning on a pivot, l', operating the lever L which isattached to the shaft of friction-pulley F, so that pulley F may bewithdrawn or applied to friction-pulley F at pleasure, the disconnectingof pulleys F and Fl causing all the machinery operated from pulley F tocease to work.

This machine may be used for turning many other articles besidesclothes-pins.

Having thus described our invention, what we claim to` have invented,and desire to secure by Letters Patent, is n i l. The revolvingspindles, constructed and operated as described, in combination with thesaws S S S and the stationary cutter l, constructed and located,relatively to the spindles and the saws, in the manner set forth.

2. The revolving spindles supported by the circular rotary frames, incombination with the feed-wheels u u and springs, arranged as described.

3. The revolving and rotating spindles having the grooves on, andprovided with the slides, Fig. 3, constructed as described, andsupported on the rotary frame'and operated positively by the stationarycam W, as speciiied.

4. rEhe wheel w1, provided with a series of clutches operated by cam102, in combination with the revolving spindles carrying the pinblanksfor the purpose, by an automatic operation, of taking each turnedpin-blank from the spindles and presenting it to the operation of theslotting-saw S.

5. The combination of set-screws a and a. with the hinged frame 7, forthe purpose of adjusting' the saws S S S, for the purpose described.
